Reaching New Levels in Groundwater Monitoring
As regions around the world face record-breaking droughts, researchers are using seismology to track groundwater levels and show that sustainable policies reduce strain on aquifers.
Salt Spray May Stifle Lightning over the Sea
New research suggests that sea-salt aerosols seed large raindrops that starve clouds of water needed to make lightning. But not all scientists are convinced it’s simply about salt spray.
Una explosión de radiocarbono del pasado
El fechamiento por radiocarbono es un pilar de la climatología y la arqueología. Sin embargo, esta metodología se encuentra amenazada por las emisiones de combustibles fósiles, que invalidan una señal útil proveniente de pruebas nucleares.
U.S. Streams Are Drying Up
A new study reports that streamflow drought is getting more intense in some parts of the United States, a phenomenon that is stressing the nation’s water policy and infrastructure.
An Inclusive Approach to Oceangoing Research
